A gas inlet module has been designed to introduce reference gases of any type, inert or combustible, into a gas chromatography/combustion -isotope ratio mass spectrometer (GC/C-IRMS) to overcome problems of mass discrimination occurring in the combustion interface. Its design permits the introductio
## Abstract This study was directed towards investigating suitable compounds to be used as stable isotope reference materials for gas chromatography combustion isotope ratio mass spectrometry (GCβCβIRMS) calibration. Several compounds were selected from those used in the βGrobβtestβ mixture. Oxygen
